Building permits, zoning and septic rules across Texas counties

Texas has 164 counties without a residential building permit requirement, 77 with requirements limited to particular cases, and 13 with a building permit requirement^1,6. Start with Cherokee County, Sabine County and Angelina County, which fall in the no-residential-building-permit group¹. Browse the Texas no-building-codes list for the full comparison¹.

A missing building permit requirement does not establish an exemption from construction standards: Texas county residential-code authority can apply without authorizing prior approval of new residential construction¹⁰. Texas also has mandatory codes specifically for industrialized housing and buildings; that program is not a universal code adoption for all site-built construction¹¹. Owner-performed electrical work has a state licensing exemption only for a dwelling the owner owns and resides in, and local building permits or inspections are not waived⁸.

Texas has 246 counties without countywide zoning, while 8 counties have zoning in applicable areas^2,6. Cherokee County, Sabine County and Angelina County are among the counties without countywide zoning². Texas county zoning authority is geographically or subject-matter limited, rather than a general statewide grant of county zoning power¹².

For buyers seeking both conditions, 158 Texas counties have neither a residential building permit requirement nor countywide zoning⁷. Use the no-zoning list and the no-building-codes and no-zoning list to narrow your search^2,7. Septic approval remains a separate question, because Texas generally requires an OSSF permit and approved plan even where a county does not require a residential building permit^1,3.

Texas septic authority is split among county offices in 189 counties, districts in 19, and state offices in 46⁶. Local TCEQ-authorized agents administer most septic permitting; TCEQ regional offices issue septic permits where no local jurisdiction is authorized, and local programs may be stricter than state minimums³. The TCEQ OSSF contacts page links to the local permitting authority lookup¹³.

Texas generally requires a permit and approved plan to construct, alter, repair, extend or operate an OSSF³. The exemption for a tract of at least 10 acres requires a licensed site evaluator or professional engineer, only a single-family dwelling on the tract, no nuisance or groundwater pollution, disposal on the property, and all system parts at least 100 feet from the property line, along with applicable planning and construction standards³. Ask the identified septic permitting authority to confirm exemption eligibility and the application fee before budgeting for wastewater approval³.

Texas RV occupancy answers cover 227 counties: 219 allow it, 7 impose limits and 1 prohibits it; 27 counties remain unanswered⁴. Tiny-home occupancy answers cover 231 counties: 228 allow it and 3 impose limits, with 23 unanswered⁵. An unanswered county is not an allowance or a prohibition^4,5.

Cherokee County, Sabine County and Angelina County are listed as allowing RV occupancy, with answers scoped to county zoning restrictions on unincorporated land⁴. Those counties also have allowing answers for tiny-home occupancy under the same county-zoning scope⁵. Compare the RV-living list and tiny-home list before choosing a county^4,5. Off-grid wastewater still generally requires an OSSF permit and approved plan; choosing an RV or small dwelling does not establish a sanitation exemption³.

Cherokee County and Sabine County lead the Texas Bolthole Index at 88, followed by Angelina County and Jasper County at 87⁶. These counties have no residential building permit requirement and no countywide zoning; Cherokee and Sabine use county septic authorities, while Angelina and Jasper use district authorities⁶.

Across Texas counties, the median county farmland value is $2,782 per acre; that is an agricultural land-value measure rather than a price quote for a particular building tract⁶. Roberts County has the lowest listed farmland value at $950 per acre, followed by Val Verde County at $1,000⁶. The median county effective property tax rate is 1.25%, and the median county property tax bill is $1,875 annually; these county medians do not establish a particular parcel’s tax bill⁶.

Texas combines surface-water appropriation and riparian or vested rights with the groundwater rule of capture¹⁴. Groundwater conservation districts generally require well permits unless an exemption applies; a particular well’s exemption and additional requirements depend on district rules⁹. A domestic or livestock well on more than 10 acres producing no more than 25,000 gallons per day has a groundwater-district production-permit exemption, but spacing and registration requirements may still apply¹⁴. Ask the applicable groundwater conservation district about the proposed well before arranging drilling⁹.

For a new or revised driveway onto state highway right of way, contact the local TxDOT district office and submit Form 1058, Permit to Construct Access Driveway Facilities on Highway Right of Way¹⁵. Construction on the right of way must wait for a fully executed driveway permit and advance notification to TxDOT of 24 hours¹⁵.
